Specification of Letters-Patent. .Pafented June 18,1918.

Application filed August 3, 1917. Serial No. 184,194. I

To all whom it may concern:

Be it known that I, PETER KIMAGK, a citizen of the United States, andresident of St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Combined Railroad -Rails and Joints, ofwhich the following is a specification containing a full, clear, andexact description, reference being had to the accompanying drawings,forming part hereof.

My invention relates to improvements in combined railroad rails andjoints and has for its object the construction of a railroad railprovided with the usual ball and having a base flange provided withzigzag recesses to prevent the rail from creeping, and the said railbeing further provided on its web portion with a series of ribs, whichincrease the strength and the rigidity of the rail, and a furtherprovision of fish plates, provided with longitudinal recesses adapted toreceive the ribs on the web portion of the rail, thus forming at thejuncture of the rails, a practically rigid joint.

In the drawings:

Figure l is a transverse section of the rail and fish plates taken onthe line 11 of Fig. 3 looking in the direction of the arrows;

Fig. 2 is a bottom plan view of the rail base; and

Fig, 3 is a side elevation of rail sections and the fish plates appliedthereto forming a rail joint.

Referring to the drawings by numerals, 4 indicates the ball of myimproved railroad rail which is of the usual standard construction foran eighty pound rail. 5 indicates the rail base which is provided on itsunderneath surface with a series of zigzag depressions 6 extendingtransversely of the rail base to within about three-quarters of an inchfrom the edge on each side; said depressions are about one-eighth of aninch deep, about one inch apart from center to center and about one-halfinch wide, and are formed throughout the rail length. The function ofthese recesses, is to prevent the rail from creeping on the ties whenthe rail is positioned on the ties; the walls of the recesses will workand cut their way into the ties and thus prevent longitudinal andlateral movement of the rail. 7 indicates the web of my improved railwhich has a central portion 8 of the standard thickness for an eightypound rail, and where the web is joined with. thehead 4: and base flange'5, the thickness is somewhat greater as shown in Fig. 1. Formedadjacent to the-base flange 5 but spaced apart therefrom on each side ofthe web, there is a longitudinal rib or projection 10, and

formedadjacent to thehead 4 but spaced apart therefrom on each side ofthe web, there is a'longitudinal rib or projection 11;

the ribs 10 being spaced apart from the ribs 11. The function of theseribs is to strengthen the web, both vertically and laterally and furtherin forming the joint; these ribs answer as brace shoulders for shoulderscarried by the fish plates. In Figs. 1 and 3 I have illustrated a railoint wherein my improved rail is used. In making the joints, especiallydesigned fish plates 12 and 18 are employed. These fish plates are alikein construction and the novel feature of construction of the fish platesis a provision on the inside face of the fish plates of a longitudinalgroove 14 in the fish plate 12, and a longitudinal groove 15 of the fishplate 13 adapted to receive the ribs 11.

of the web, and longitudinal grooves 16 and 17 adapted to receive theribs 10. When my improved fish plates have been applied, it will beobserved that the rail is supported by its head 4 resting on the top ofthe fish plates and also the ribs 10 and 11 resting in recesses formedin the fish plates. In other words, the fish plates support the rail inthree places, thus making a perfectly rigid joint. My improved rail isnot only highly desirable informing a rigid joint as herein described,but by its construction forms a very strong rail between the joints, asthe ribs carried by the web add strength and rigidity to the railthroughout. In fact, an eighty pound rail constructed according to myinvention is approximately as strong as a one hundred pound rail of theordinary construction.

While I have shown two projecting ribs on each side of the web, thisnumber may be varied, and the position of the ribs may be differentlylocated with respect to the ball and base; and while I have shown myimprovement on an ordinary running rail, the same may be used 011 asiding rail and it is especially desirable for a switch point rail. Itwill be noted that a switch point rail constructed with thestrengthening ribs as shown, will be much stronger and resist morelateral pressure than those with an ordinary web. In the manufacture ofmy improved rail, the 'ribs or projections are formed on the websimultaneously with the rolling of the rail, and the depressions 6 arealso formed by rolling.

Having thus described my invention, what I claim is:

A combined rail and joint comprising a rail provided with a ball, web,and base flange, said base flange beingprovided on its underneathsurface with a smooth plain margin on each side, and with a ,series ofzigzag depressions formed intermediate of and extending above saidmargins, and the web of said rail being vprovided on each side with aseries of parallel longitudinal ribs there being bolt openings betweenthe ribs and spaced therefrom, and a pairofifish plates provided withrecesses or grooves adapted to receive the ribs of the rail web, thesaid fish plates being provided with spike openings.

In testimony whereof, I have signed my name to this specification, inpresence of two subscribing witnesses.
